My; invention relates to: a vertically' adjustable floor pivot mounting for a panel or doorarranged to carry a bed in up-ended position for'movemen't through a wall-openIng 5 engaged by the panel, adjustment of the panetafter installation; beingoften neces sary due to'the settling'of the building, sagging of thepanel, clearance for rugs, etc. An object of the invention is to provide an adjustable pivot mountingofthe character described which will have permanently combined therewith complete, self-contained means operatable without disturbing the panel or parts supported thereby, for effecting the adjustment thereof and maintaining the same in adjusted "position.

Another object of the invention is to' provide means of the character described, having adjustment maintaining means which in its normal operative position will lie inconspicuously disposed in the floor, and must be temporarily displaced from such position before readjustment of the mounting may be efiected.

features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the 3 drawings accompanying and forming part of thespecification, "It is to be understood that I do not limit, myself to the showing made by the said drawings and description,

as I may adopt variations of the preferred forth in the claims.

Referring to said drawings:

' Figure 1 is a verticalsectional view taken through the pivot mountin'g'and associated portions of the floor and bed-supporting panel. i

Figure 2 is a plan view of the portion of the device arranged to be directly associated.

with the floor.

Figure 3 is a sectional plan of a bed installation provided with the device of my invention. Y

Figures 4: and 5 are views similar to Figures 1 and 2, illustrating a modified formof 5c the invention. i

As illustrated in the drawings the pivot mounting 6 of my invention is particularly adapted for use in supporting upon a floor 7, a wall section, door, or panel 8, or similar member, on which a foldable bed 9 is adapted to be carried in tip-ended position for mot? The invention possesses, other objects and 7 form within the scope of my invention as setv ment through'an opening of a walljlO, such movement of the bed serving to transfer it from one room to another, oi, as here shown, from a'room 12 to acloset 12 or vice versa.

Referring now particularly to Figures 1 and 2, the device comprises a base member '14 having a plate portion 16 and a depending hollow "boss 17. The plate 16 is arranged to be positioned, particularly when installat on is beingmade in a buildingunder construc tion', on the sub-flooring or sheathing 18 upon whichitheusual layer 19 of hardwood is laid,

. Theplate ispreferably of the same thickness as the layer 19 so that the top surfaces of the plate and floor will be flush.

The boss 17 of the base is' provided ad-' jacent the bottom withja threaded portion 21inwhich is arrangedto engage the thread ed end 22 of one ofthe cooperating pivot members 23 and 2a of the device. The pivot members are of a semi-ball and socket type,

and in the'present embodiment the member 23 which contains thesocket" is arranged to be associated with the base and :is thus formed with the threads 22 The pivot member' 24 contains the pivot stud 25 and is attached to the panel adjacent the lower edge thereof means ofa bracket 27 preferably formed integral with the stud.-

'n will now be clear that rotation (if the socket meniber23 will vary its position verti cally, thereby justment of the panelin the wall opening. Means are'thereforeprovided "for rotating the member 23 and then locking it against rotation after the desired vertical adjustment has been secured, said means as hereinbefore pointed out being self contained, complete, and 'sodesigned that in normal operative position it will lie inconspicuouslydisposed in the floor, tirely ance with the foregoing, the base 14 is formed with a depression 28 which, as here shown, is arranged in the plate 16 and extends longitudinally thereof. Normally lying within the depression and being substantially of the same shape as the depression is a lever 29 having an end 31 arranged to en causing a corresponding ad-i preferably practically enbelow the surface thereof. In accord- 7 gage the member 28. The member 23, is 7 preferably formed with a polygonal exterior 5 and the portion of the lever engaging same is correspondingly formed. In this manner with the lever seated in the depression and engaging the member 23, the latter will be positively held against rotation and verti depression.

However, should conditions, such as the sagging of the panel, make necessary, a variation or adjustment of the position of the panel in itsopening, the lever may be raised vertically from the depression to operate above the top plane of the floorand so be used to rotate the member lVithdrawal of the lever from the depression by the operator, is facilitated by the provision of recesses 82 which are disposed at thev sidesfofjthe depression and permitthe operatorv to gripthelever while it repose i i the After he at r. h s. been '9- tated sufficiently to bring tl1e,1nember23 to e d sired h e'l' t, t e lev is a owed o ga n. sea in, the epres io th he end. 3

InFigu s t a i h n, a ightly modifiedformof the invention. In this embodiment, the handle portion, of the lever is omitted, and as a result, a member 33 resembling a nut is seen in the place of the leve,r., The function of the member 83. is similar to that, of the, lever, with, exception that in order to rotate the socket member 23 a separate wrench or other tool (not shown) is required, the latter being arrangedto be applied either to member 38 or directly to.
